Restless

A large green mob that resembles a Warden that appears in the forest. This mob is quiet during the day, but becomes ferocious at night or in the dark, such as in a cave. Also, this mob only looks dark, becomes almost blind during the day, and suddenly becomes quiet. This mob is weaker than Warden, but slightly stronger than Iron Golems. The tricky part of this mob is its ability to mimic. Warden responds to vibrations, while restless is a mimicry ... If Warden were to be a disaster in Minecraft, this restless would also be a new disaster in another sense ... If you have any other good ideas, let us know in the comments. Thank you for taking a look at my thoughts.
